While avian chronic haemoparasite infections induce reproductive costs, infection has not previously been shown to affect survival. Here, we experimentally reduced, through medication, the intensity of infection by Haemoproteus parasites in wild-breeding female blue tits Cyanistes caeruleus. However, this treatment did not reduce the intensity of infection in males or the intensity of infection...
Thirteen of 21 nestling bald eagles (Haliaeetus leucocephalus) examined for blood parasites in Michigan and Minnesota (USA) during June and July 1997 had patent infections of Leucocytozoon toddi. No other parasites were seen. The degree of parasitemia was light and varied from 1 to 2 on the Ashford Scale. Several of the infected nestlings appeared to have elevated levels of heterophils in their...
Birds may be host to a number of species of blood-inhabiting protozoa and nematode worms transmitted by haematophagous arthropods. Protozoan parasites include haemosporidia in the genera Plasmodium, Haemoproteus, Leucocytozoon, Hepatozoon, and Babesia, and haemoflagellates in the genus Trypanosoma. Most families of birds are susceptible to blood protozoal infection in the wild (Bennett et al. 1...
Bloodsmears were taken from separate groups of five helmeted guineafowls, Numida meleagris, shot at approximately monthly intervals at Skukuza and near Lower Sabie in the Kruger National Park during the period August 1988 to August 1990. Ninety-eight (86%) of 114 guineafowls had single or multiple infections of Aegyptianella sp., Haemoproteus pratasi, Hepatozoon sp., Leucocytozoon neavei, Plasm...
